The Control phase is the fifth and last phase of a DMAIC process. The main activity in the Control phase is to control the improved process.
Maintaining solutions is one of the key activities in the Control Phase to ensure the new process is implemented and doesn’t revert.
Process Characterization is a method to identify and quantify the significant source of variation. It is part of the Control phase of DMAIC.
Process control for non-normal data involves monitoring and managing industrial or operational processes that produce non-normally distributed data.
Process Capability & Performance (Pp, Ppk, Cp, Cpk) are indicators of the specification relative to process dispersion and process centering.
